Patent EP-0021145-A1 (EP)
Inventor: CHOQUET MICHEL FRANCOIS
IPC: H04J3/00
Filed: 1980-06-03
Abstract: A digital data communication system uses a common channel (22) to carry both normal messages and supervisory messages, the latter being inserted into the message stream during intervals between normal messages. Each transmitting location has a switch (16) with three settings. Setting 1 enables data to pass from the normal message generator directly to the channel. Setting 2 enables data to pass indirectly from the normal message generator through a delay line (X1-X2-X3) to the channel. Setting 3 enables data to pass from the supervisory message generator to the channel. A switch control (24) comprises message status detecting circuitry associated with the delay line. This switch control enables the switch to assume setting 3 when no normal message is being generated and a supervisory message is awaiting transmission. When the supervisory message ends, the switch is controlled to assume setting 1 if the delay line contains no significant normal message data nor any indication that an out-of-synchronism condition exists; otherwise the switch assumes setting 2 until the delay line is cleared of normal message data or reaches a synchronous state, as the case may be, whereupon it returns to setting 1. Each supervisory message has a distinctive format which enables it to be recognized at the receiving location and diverted from the message stream to a supervisory message receiver before it can enter the normal message receiver.

Title: Power-driven centrifugal air blower
Inventor: RUSSELL JOHN VICTOR ANDREW
IPC: F04D23/00
Filed: 1980-07-17
Abstract: A power-driven centrifugal air blower whose rotary impeller (15) takes the form of a generally cylindrical brush. The brush is comprised of a relatively dense mass of bristles each of which extends substantially radially from a central hub. The bristles thus replace the multiple individual blades of the impeller used in a conventional power driven centrifugal air blower. Preferably they are sufficiently relatively spaced apart from one another, and made of suitably non-electro-static material, that essentially no filtration of the indrawn air takes place as the air passes through the impeller.
